The 27-year-old France international has been linked with a summer move away from St James' Park but he insists he is fully focused on helping the Magpies avoid relegation from the Premier League.
He said: "I have three years' contract left and now my mind is just to save the club. We have two cup finals then it will be the holidays.
"But I am at Newcastle. I don't want to think about the future with two games left. I am very, very happy to play for this club and these fans."
Cabaye admits Newcastle's performances this season have not been good enough and is looking for considerable improvement next term.
He said: "We all made some mistakes at the start of the season - that's why we are fighting for relegation.
"But if we learn from our mistakes, no problem. We are only human and we all make mistakes, but now is time to learn and prepare.
"We need to finish strongly and then prepare well for next season. We have to be ready to fight and play and be ready again in the Premier League, like we were last season."
